# Neobrutalism

## Overview

硬边、硬阴影、一记明黄，海报贴在墙上。 整体气质是 日常应用适中、艺术化不规则、动效 流畅 CSS 动效。品牌语气：loud / graphic / honest。密度 6/10，变化 8/10，动效 4/10。 材质：2px 实线边、硬偏移阴影、圆角接近 0。禁止模糊阴影和渐变。

How to use: 把本文件放到仓库根目录。在 Cursor / Claude Code / Codex 提示词中写：请阅读 DESIGN.md 并严格遵守其中的 tokens 与 Do/Don't。

## Colors

Semantic roles for the light theme. Keep a single accent; do not introduce a second brand hue.

- **primary** (`#111111`)
- **secondary** (`#111111`)
- **tertiary** (`#FFE500`)
- **background** (`#FFFCEB`)
- **surface** (`#FFFFFF`)
- **outline** (`#111111`)
- **muted** (`#444444`)
- **success** (`#1F7A4D`)
- **warning** (`#E0A100`)
- **error** (`#E11D48`)
- **onPrimary** (`#F4F4F5`)
- **onSecondary** (`#F4F4F5`)
- **onTertiary** (`#18181B`)
- **onBackground** (`#18181B`)
- **onSurface** (`#18181B`)

## Typography

Hierarchy comes from weight and size, not from shouting. Body line length stays near 65 characters.

- **h1**: "Space Grotesk" 700 / 56px / 1.02 / -0.04em
- **h2**: "Space Grotesk" 600 / 36px / 1.2 / -0.02em
- **h3**: "Space Grotesk" 600 / 20px / 1.3 / -0.01em
- **body**: "Space Grotesk" 400 / 16px / 1.55 / 0em
- **label**: "Space Grotesk" 500 / 13px / 1.3 / 0.02em
- **caption**: "Space Grotesk" 400 / 12px / 1.4 / 0em
- **mono**: "JetBrains Mono" 500 / 13px / 1.45 / 0em

## Layout

Spacing scale: xs=4px, sm=8px, md=16px, lg=24px, xl=32px, 2xl=48px, 3xl=64px.

iOS：触控目标 ≥ 44pt，尊重 Safe Area 与 Dynamic Type，图标用 SF Symbols，导航使用 Large Title / 分组列表。

Web：移动优先，<768px 单列，正文 ≥ 16px，标题用 clamp()，容器 max-width 约 1120–1400px，全高区块用 min-h-[100dvh]。

Every element occupies its own spatial zone. No overlapping hero text. Collapse multi-column layouts below 768px.

## Elevation & Depth

- sm: `2px 2px 0 #111`
- md: `4px 4px 0 #111`
- lg: `8px 8px 0 #111`
- surface: `brutal`
- recipe: 2px 实线边、硬偏移阴影、圆角接近 0。禁止模糊阴影和渐变。

Tint shadows toward the background hue. High-density layouts may replace cards with hairline dividers.


## Shapes

Radius scale: sm=0px, md=0px, lg=2px, xl=4px, full=999px.

## Components

- **导航栏** (`web.navbar` / default / md): 桌面横导航含 logo、带图标的链接和一个主 CTA。
- **Hero** (`web.hero` / center / lg): Hero 使用 center 布局，最多一个主 CTA，禁止「Scroll to explore」。
- **媒体位** (`media` / wide / md): 几何封面位，圆角跟 tokens。禁止远程图。
- **列表行** (`list-item` / chevron / md): 行高至少 44pt，标题 + 说明，右侧可放 chevron。
- **列表行** (`list-item` / chevron / md): 行高至少 44pt，标题 + 说明，右侧可放 chevron。
- **列表行** (`list-item` / chevron / md): 行高至少 44pt，标题 + 说明，右侧可放 chevron。
- **行动条** (`web.cta` / default / md): 单条 CTA，禁止双按钮并列抢焦点。
- **页脚** (`web.footer` / default / md): 页脚克制，链接分组清晰。

## Do's and Don'ts

### Do
- Use semantic color tokens, never raw hex in components.
- Keep a single accent; hierarchy comes from type weight and space.
- Define default, hover, focus-visible, pressed, disabled, and loading states.
- Meet WCAG 2.2 AA contrast for body text and interactive labels.
- Touch targets are at least 44×44pt on iOS and 44px on web.
- Keep borders 2px and shadows offset, never blurred.

### Don't
- Do not use Inter as the display face for premium work.
- Do not use pure black #000000 for large surfaces.
- Do not add neon outer glows or custom mouse cursors.
- Do not ship three equal feature cards as the default layout.
- Do not hide focus rings or drop below AA contrast.
- Do not soften corners or add gradients.
